No audio output device is installed

the sound icon on the task bar has a red X cursor and displays this message. however, in device manager, all 3 of my sound drivers are installed and are listed as working properly. then, in control panel>sound, no devices are listed.

i have tried scanning for hardware changes, disabling/re-enabling drivers, and uninstalling the drivers then restarting my computer to let windows reinstall them. no solutions thus far.

i am using windows 7 64, HT omega striker 7.1 sound card, and HDMI from an HD 5770. any help would be appreciated.

Have you already tried the latest Rev.81740 driverset? And if you haven't already, check out this thread...

thanks for the reply, redduc. i have the latest rev, and i read through that thread you posted. i will try uninstalling/reinstalling the drivers (some in that thread suggested removing the hsmgr.exe file before reinstalling).

but would my sound card keep my computer from recognizing all of my sound outputs (video card, sound card, and motherboard)??

It shouldn't. I switched from Realtek to ATI to Xonar on the same system with all 3 hooked up and it recognized and switched around no problem.

As did I for months (until yesterday), even currently in device manager all three drivers are showing up as enabled and working properly. however, the sound manager in control panel is listing no devices and there is a red x over the volume icon in the taskbar.
